While other workplace apps might only be necessary for certain departments, messaging is the thread that ties a business together. The move takes advantage of the fact that everybody in a company needs chat. Rather than having to remember a login and password for every different workplace app, you’ll be able to just use your Slack login. “Sign in with Slack” could turn Slack into the identity provider for the enterprise. Now Slack is colonizing the enterprise landscape beyond the walls of its own app. Today, the company is unveiling a new feature called “Sign in with Slack” - which will let Slack users sign into and use other apps using their Slack identities. One of its chief hooks is the ease with which you can integrate lots of different apps so that you can communicate about work within each of them all in one place. The workplace chat app has already captured the eyes, minds (and wallets) of the tech world with its deceptively simple, zippy platform for people to communicate and collaborate with each other on projects. Slack is pushing to become the identity layer for all enterprise apps.
